Abstract

Wild edible plants provide the local people with food and medicines and are considered one of the natural ecosystem services. These wild edible diets and herbal medicine always reflect local communities' regional identity and their traditional ecological knowledge. In the new global economy, the natural product field has become a central issue for preserving the traditional culture related to nature, particularly in the context of a sustainable environment. This research study aims to determine the nutritional value and phytochemical contents in a wild population of Allium calocephalum. This wild edible garlic, endemic to the Zagros mountains, is overharvested by Kurdish rural people to enhance their food security at a household level and to perpetuate the preservation of their natural heritage. Here, we estimated the total phenols, flavonoids, carbohydrates, protein, fibers, ash, oil yield, and significant mineral content in both leaves and bulbs of A. calocephalum. Phytochemical analyses were conducted at the Faculty of Agricultural Engineering Sciences (University of Duhok) and the environmental directory of Duhok, Kurdistan Region of Iraq, to get an overview of its nutrients and phytochemical values. Interestingly, a high level of phenolic compounds was obtained from bulbs (0.684 mg gallic acid equivalents/g of dry extract, eq.100g-1). The lowest level of phenolic compounds was found in leaves (0.522 mg gallic acid equivalents/g of dry extract, eq.100g-1). Simultaneously, the bulbs extract gave higher content of flavonoid compounds than the leaves extract (6.31 and 4.73 μg quercetin equivalents/g of dry extract, eq.100g-1, respectively, for the bulbs and leaves). The highest dry weight basis of total carbohydrates, energy value (Kcal), oil content, and moisture content were observed in bulbous parts, and the values were 71.75, 408.86 (Kcal), 9.52, and 92.37, respectively. On the other side, the highest dry weight basis of total protein, fibers, and Ash content was observed in shoot parts, and the values were 15.93, 13.89, and 9.32, respectively. The evidence from this research study supports the idea that this Zagrosian endemic wild garlic enhances the food security and the nutrient diet values of the rural Kurdish people.
